| Abstract: | On the basis of the definition of the magnetic field line and the distribution of magnetic field around an uniform magnetized sphere, the article resolves a differential equation and deduces a simple expression of the magnetic field lines,which makes it easy to draw the magnetic lines for an uniform magnetized sphere in geomagnetic research. |

| Keywords: | geomagnetic field uniform magnetized sphere magnetic dipole magnetic field line |
